Yes, that's the only thing you can play with in 3rd party SODE jetways.
With GSX SODE jetways, we can be 100% precise, since we have two floor heights: one used by SODE to align the jetway to the airplane door, and a separate one used by GSX as a walkable floor for passengers, since they are not exactly the same. But this is an data known to GSX only, which SODE doesn't need or use.
With 3rd party SODE jetways, the separate passenger floor parameter is not available, so we use a standard correction factor of 15-20 cm which will be added to the SODE root floor height parameter, so you won't see the passenger feet under the jetway but, of course, it cannot always be 100% right because:
- Different jetway models might have their floor of varying "thickness" ( the difference between the jetway bottom floor and the walkable floor )
- The root floor height of the 3rd party jetway might not be accurate to begin with.
